How does a city enforce a breed-specific law?
The model for most cities is to “enforce as you go.” Authorities take action as they become aware of infractions or as complaints are received. For example, the City of San Francisco issues a “Fix It” ticket when a person is caught having an unaltered pit bull. The owner then has two-weeks to fix the dog. If the owner fails to provide proof of surgery after this time, he or she is fined $500.
